Subject: [PATCH] [test] Use LD_LIBRARY_PATH to ensure that a new lib is used
(#1989)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Add the library `BINARY_DIR` to `LD_LIBRARY_PATH` to ensure that
the freshly built `libLLVMSPIRVLib.so` is tested. Otherwise, llvm-spirv
spawned by the test suite may use the previously installed
`libLLVMSPIRVLib.so`.
I have noticed the problem after rebuilding LLVM with
`-DLLVM_ENABLE_ASSSERTIONS=ON`. This meant that the previous version
of `libLLVMSPIRVLib.so` now crashed, effectively causing the test suite
to fail incorrectly.
